    5. 5. LSMW Introduction
    6. 6.  What is LSMW?  The Legacy System Migration Workbench is an R/3 based tool that supports, when transferring data from non-SAP systems ("Legacy Systems") to SAP systems once or periodically.  It supports conversion of data of the legacy system in a convenient way.  It can be imported data into the SAP system via batch input, direct input, BAPIs or IDocs.
    7. 7.  Supported Releases   Version 1.7 of the LSM Workbench can be used in R/3 systems with 4.0A and above maintenance levels. Basic Principles of the LSM Workbench  The LSM Workbench was developed on the basis of the R/2R/3 Migration Workbench.  Business objects instead of individual tables or field contents are migrated.  The conversion rules to be defined are flexible.  Preprogrammed conversion programs are generated on the basis of the defined rules.
    8. 8.  Most of the functions should reside in the SAP system. No collection of individual programs on different platforms.  The quality and consistence of the data imported into the SAP system should be more important than speed and performance of data migration.  Existing knowledge and coding should be used.  The developed "mapping" and rules should be reusable and thus be used repeatedly in projects.

    10. 10.  Advantages of the LSM Workbench  Part of the SAP system and thus independent of individual platforms.  A variety of technical possibilities of data conversion.  Data consistency due to standard import techniques:  Batch input  Direct input  BAPIs (Business Application Programming Interfaces)  IDocs (Intermediate Documents) The import technique to be used in an individual case depends on the business object.
    11. 11.  Generation of the conversion program on the basis of defined rules.  Clear interactive process guide  Interface for data in spreadsheet format.  Creation of data migration objects on the basis of recorded transactions.  Charge-free for SAP customers and SAP partners.
    12. 12.  Preconditions  Make sure that SAP customizing is finished.  Determine the data contained in your legacy system and which of the data will be required in the future (with respect to business operation).  Decide whether it makes sense to use this tool with respect to the data volume to be transferred.  Identify the transaction(s) in the SAP system via which you want to import the data into your SAP system. It may be relevant whether you need the data for statistical analysis or for further processing in the system.
    13. 13.  Run the relevant transaction in the SAP system manually with test data from the legacy system and see which fields must be filled. There may be required fields that do not correspond to data fields in the legacy system. In such a case, you should better assign a fixed value or establish an optional field for data transfer.  Map the fields in advance in written form: Assign the source fields to the target fields.  Determine the form in which non-SAP data will be transferred into the SAP system (e.g. via "Move" or according to a rule).  If applicable, define the translation rules (LSMW-internal name: "translation").
    14. 14.  In which way will the data be extracted from the non-SAP system? Note: The LSMW does not extract data.  In which form is the legacy data available? Determine accordingly which of the LSMW functions will be applied.  If only a part of your legacy system will be replaced by SAP, determine which function will be provided by the SAP system and which by the legacy system. If applicable, set up a concept of data flows and interface architecture.
    15. 15.  Initial Transaction To start working with the LSM Workbench, use transaction LSMW:
    16. 16. mySAP ERP  Project, Subproject and Object  On the initial screen, you can create a new project, corresponding subprojects and objects via Edit -> Create new entry.  Project:  Subproject: An ID with a maximum of 10 characters that is used as further structuring attribute.  Object: An ID with a maximum of 10 characters to name your data transfer project. If you want to transfer data from several legacy systems, you may create a project e.g. for every legacy system. An ID with a maximum of 10 characters to name the business object.
